Blogger Bert Webb discusses the latest book by British writer Danny Wallace, who spent a year saying, "Yes," to every opportunity given to him in hopes of getting out of a bit of a funk.

Though the results of Wallace's "Say Yes More" mantra range from amusing (knowingly entering into an Internet scam) to surprisingly effective, it certainly reminds us that negativity can serve as a barricade to progress and opportunity.

When I heard Danny on a radio interview tell of his experiences, I immediately thought of endless meetings at work where ideas were brought up and then shot down in a flurry of negativity. "No! We can't do that!" "We've never done that before." "That won't fly here." "We don't have the resources." It seemed like no idea was bullet-proof. As a result, very little was done. What we got was the status quo.

I'm curious, Lifehacker readers - when have you said, "yes," when it might have been much easier to say, "no," and what was the outcome? Let us know in the comments or at tips at lifehacker.com.
